Removing the PCA
Step 1. Lift the two latches on both the right top
and left top corners of the rear access door
to unlatch it.
Step 2. If you have any peripheral accessory (e.g.
MIO network card), remove it by
loosening the two screws on the card and
slide it out from the right side of the rear
access door. Set the card aside.
Step 3. Unscrew the four screws on the metal
PCA cover and set them aside. Remove
the PCA cover.
Step 4. Unplug all connectors (two in black and
two in grey) and the power connector
(blue) from the main PCA.
Step 5. Carefully remove the two flex cables from
the main PCA by lifting the black plastic
fastener at both ends and sliding the flex
out.
